Definition of "Internet"10/24/95
On October 24, 1995, the FNC unanimously passed a resolution defining the term Internet. This definition was developed in consultation with the leadership of the Internet and Intellectual Property Rights (IPR) Communities.
RESOLUTION:
"The Federal Networking Council (FNC) agrees that the following language reflects our definition of the term "Internet".
"Internet" refers to the global information system that --
(i) is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons;
(ii) is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols; and
(iii) provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein."

Packet Switching Slices digital messages into packets Sends packets along different communication paths
as they become available Reassembles packets once they arrive at destination Uses routers
Special purpose computers that interconnect the computer networks that make up the Internet and route packets
Routing algorithms ensure packets take the best available path toward their destination
Less expensive, wasteful than circuit-switching

TCP/IP Transmission Control Protocol (TCP)
Establishes connections among sending and receiving Web computers
Handles assembly of packets at point of transmission, and reassembly at receiving end
Internet Protocol (IP) Provides the Internet’s addressing scheme
Four TCP/IP layers Network interface layer Bits to media specific “pulses” Internet layer addressing and routing Transport layer sequencing packets (providing “flow” control) Application layer providing services to end user
